, To all whom it may concern."

Be it known that I, GEORGE E. HEID- nnnnnln a citizen of the United States, re-

siding at Quincy, in the-county of Adams, State of Illinois, have invented a new and useful Coal and Gas Range; and I do hereby declare'the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved.

combination coal and gas range, and one of the objects ofthe invention is to provide a device of this kind, which is simple, efficient' and practical in construction andso constructed that it may be easily converted, whereby either coal or gas may be used.

Another object of the invention is to improve the coal and gas ranges shown, set forth and claimed in the prior patents to George E. Heidbreder issued respectively.

October 19, 1915 and March 28, 1916, Patent Nos. 1,156,999 and 1,177,244.

A further object of the invention is to provide a passage for the products of combustion from the fire-pot leading over the oven and down adjacent the end of the oven opposite the fire-pot, under the oven, and deflected into and through an exhaust flue.

A further object of the invention is the provision of a gas chamber and burner there:

inand provided with passages of commun'i-.-

cation with the oven, in combination with an exhaust passage from the oven communicating with the flue for the products of combustion from the fire-pot,whereby should the heat in the oven from the gas chamber increase, it is automatically carried off through the said flue and then under the oven and deflected into and through the ex- A further object of the invention is to provide means for controlling the passage of heat from the oven to and through the said flue.-

A further object of the invention is to providemeans for controlling the gas burner and the controlling damper of the oven simultaneously.

In practical fields the details of construction may necessitate alterations falling within the scope of what is claimed.

The invention comprises further features and c mbinations of parts, as hereinafter Specification'of Letters Patent.

COAL AND GAS RANGE.

set forth, shown in the drawings and claimed.

In the drawings :Figure l is a plan view of the improved combination coal and gas range constructed in accordance with the invention. Fig. 2 is a vertical sectional view on line'2 2 of Fig. 1. Fig. 3 is a transverse sectional view on line 33 of Fig.2. Fig. 4 is a vertical sectional view on line 44.- of Fig. 2.

Referring more especially to the drawings, '1 designates a casing of the coal and gas range provided with the usual fire-pot 2, the grate bars 3 and the ash-pit 4. j The top plate 5 has one-half provided with the usual cooking holes 6 and cover plates 7. The other half of the top plate merges downwardly and laterally and up wardly forming a depression 8 for the usual burners 9, over which the conventional supporting bars 10 for pans and the like are arranged. The burners 9 are connected by the valve connections 11 to the usual gas supply pipe 12.

Extending from the fire-pot and over the oven 13 is a passage or flue 14, which merges into the flue or passage 15 at the end of the range opposite the fire-pot. It is to be noted that the passage 14 where it communicates with the passage 15 extends under the gas burner space 8, whereby said space, may be heated, so that pans or articles of food may be kept warm when burning coal in the firepot and not using said burners 9.

The flue or passage 15 does not extend to the front of the oven at its lower part, but

of therearpart of the top plate of the cas- I ing of the range the usual smoke flue or pipe (not shown) may be connected. 7

Adjacent one side of the port 17, a deflector plate 20 is secured, extending angularly and half way across the space or flue 16, so as to deflect the products of combustion over the entire bottom sheet of the oven and out through the port 17 and through the flue 18. Between the bottom sheet of the casing of the range and the bottom wall or sheet of the flue 16 is a gas burner space 21, in which a gas burner 22 is arranged.

- The gas supply pipe 23 is provided with the usual connection 24 with said burner 22, which connection is provided with the usual .gas cock or valve 25, to the valve stem of which an arm 26 is connected, and by grasping the hand piece 27 of said valve cock the gas may be turned on.

Secured in any suitable manner to the under face of the bottom sheet of the flue or space 16 is a-conical deflector plate or sheet 28, which deflects the heat from the burner in opposite directions and toward the flues or passages 29 and 30 at opposite ends of the space or passage 16.

The plate 31,'together with the walls 32 and 33, form the opposite sides of the flue 30. The wall '33 of one endof the oven 13, has ports 34 communicating with the flue 30 and said oven, so that the heat from the burner 22 may pass into the oven. The wall 35 extends from the front portion only of the oven wall 36 to end range wall 37, and

' the lower forward portion of this wall 35 forms the heat flue 29 from the burner 22, while the rearwardly extending portion 38 of the wall 35 extends substantially from the forward portion'of the oven wall 36 to the rear of said wall, thereby forming the space 39 but leaves a large part of the flue 15 unobstructed, as shown in Fig. 4.

i The lower part of the wall 36 adjacent the space 39 is provided with elongated openings 40, through which the heat from the space 39 may pass into the oven. The upper edges of the openings 40 have flanges 41,

which, as the heat from the burner ascends into the space 39, deflects the heat toward the upper surface of the bottom sheet of the oven.

An arched plate 42, shown in dotted lines in Fig. 2 and in section in Fig. 3, is secured on the rear sheet 43 of the range,

thereby forming the space or passage 44.

The rear sheet 43 of the rangeis provided withports oropenings 45 and 46. The port 45'forms communication between the space i 44 and the oven, while the opening or port 46 forms communication between the space 44 and the flue or passage 15.

Mounted in bearings of the plate 42 is a rock shaft or rod 48 having a crank arm 49 at one end, and provided with a damper plate 50, "which is of sufficient length to cover both openings 45 and 46. A-rod 51 has one end connected to the crank 49, and the other end to the arm 26 of the stem of the gas or valve cock 25., It is tobe noted that when manipulating the valve cock 25 to admit gas to be. lighted, the damper plate 50 is simultaneously opened, thereby uncovering the openings 45 and 46 and allowing. the heat in the oven to pass through "T the opening 45 into the space 44, through the opening 46 into the lower part of the passage or flue 15, and as there is a draft downwardly through the flue 15 into the of the oven.

space 16, the excess heat from the oven will pass off through the flue 16 under the oven sheet and out through the exhaust flue.

When burning coal in the fire-pot, the

I damper plate 50 may be closed, thereby covering the ports 45 and 46 to prevent the escape of the heat in the oven. However,

when burning coal in the fire-pot and the heat in the oven should become too great,

the excess heat may be allowed to escape, by 7 rations or apertures 53, to permit the intake of air, in order that proper combustion for the burner 22 may be had, and so that the 8 heat will travel upwardly into the oven. In other words, by providing these air holes, a draft is created, which causes the heat from the burner to ascend into the flues 29 and 30.

There is an essential feature or result attained by permitting the escape of the excess heat in the oven, for instance, in that the oven is not too quickly cooled. For example, even though the excess heat is passing out through the ports or openings 45 and 46, the intensity of such heat is not very much decreased; therefore, when such heat is passing through the lower part of the flue 15 and through the flue 16, the heat acts upon one of the end walls of the oven and the bottom sheet of the oven, and for this reason the heat in the oven does not begin to lessen until the damper plate 50 is open for a considerable length of time.

A damper 54 is mounted in the exhaust flue 18, and when the damper is closed the heat from the oven, that is the excess heat, may pass through the flue 15 and into the s ace '16, by opening the damper plate 50.

11 other words, by opening the damper 50 and closing the damper 54, the heat in the oven is given room to expand, and the excess of this expanded heat may be allowed to pass off by opening the damper 54 partially or completely.
